javascript clock with PHP date help needed

I am try to get the current server time into javascript clock where the clock starts ticking up to show the current running time but can't seem to get it to work.

The code I am using so far is:

function show2(){
  if (!document.all)
    return

  var Digital=new Date("<? echo $mytime; ?>")
  var hours=Digital.getHours()
  var minutes=Digital.getMinutes()
  var seconds=Digital.getSeconds()
  var dn="AM" 

  if (hours>12){
   dn="PM"
   hours=hours-12
  }

  if (hours==0)
   hours=12

  if (minutes<=9)
   minutes="0"+minutes

  if (seconds<=9)
   seconds="0"+seconds
   var ctime=hours+":"+minutes+":"+seconds+" "+dn
   tick2.innerHTML="<b style='font-size:22;color:blue;'>"+ctime+"</b>"
   setTimeout("show2()",1000)
}

window.onload=show2

Code (markup):

Anyone have any idea as to what I am doing wrong or have a better solution to get it to work?

Thanks in advance.

 

what is in the mytime variable $mytime can you post it here

 

<form name="Tick">
<input type="text" size="11" name="Clock">
</form>
<script>


function show(){
var Digital=new Date(<?php $mytime; ?>)
var hours=Digital.getHours()
var minutes=Digital.getMinutes()
var seconds=Digital.getSeconds()
var dn="AM"
if (hours>12){
dn="PM"
hours=hours-12
}
if (hours==0)
hours=12
if (minutes<=9)
minutes="0"+minutes
if (seconds<=9)
seconds="0"+seconds
document.Tick.Clock.value=hours+":"+minutes+":"
+seconds+" "+dn
setTimeout("show()",1000)
}
show()

</script>

Please try with this script

The above script you are using is not defined span "tick2"
